How Does An Under Counter Water Filter Work?

how does an under counter water filter work

An under counter water filter has two main parts: the faucet and the cartridge pack.

The faucet that comes with the under counter system is usually installed beside your original faucet. The faucet that is included in the under counter system package, is for filtered water only (please view diagram for illustration).

Now the water filter cartridge pack is installed below the faucet and is not visible to the public. The cartridge pack is usually attached to the wall or the cupboard.

After the water enters the cartridge, the water goes though a filtration process which is usually 2 to 7 stages of complete filtration. The filtered water is released instantly through the faucet attached to the filter system.

Most persons let their original faucet remain as well as the filter faucet. That way they can cook or clean with the tap water and drink filtered water from the new faucet.

An under sink water filter is one of the best and easiest ways to get filtered water. All you have to do is turn on your faucet and out comes the water.

Choosing An Under Counter Water Filter

  • Removal of contaminants

    Ensure that the under counter filter that you choose will remove the contaminants that you want to remove. In addition, ensure that the system will not only remove the contaminants but a high percentage of the contaminants. Always remember that there is a big difference between 97% and 99% contaminant removal percentage.

  • Price and cost per Gallon

    Be careful because there are under counter systems on the market selling for $50 and their replacement cartridge cost the same. There are also under counter systems on the market that require a replacement cartridge every 100 or 200 gallons. These under counter systems should not be your first choice because they will cost you more money in the long run.

  • Availability of parts and customer service

    You should only buy an under counter filter from a company with a good track record of excellent customer service. Remember that you will need to call customer service in case of an emergency, repair or installation. They should be able to give you step by step instructions, make you feel comfortable and satisfied.

    You should also ensure that spare parts are readily available. No one wants to wait too long for parts to fix or improve their filter system.
